P. FARWELL SAW FILE Filed July 21, 1958 2 Sheets-Sheet l Inventor .P/lz'llz Rrwell Q A ttorneys Patented Aug. 29, 1939 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to files and more particularly to a file particularly designed for filing the teeth of a raker tooth saw after the teeth of the saw have been set; and the invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a top plan view illustrating the application of the invention.

Figure 2 is an elevational view of the invention also illustrating the manner of using the same.

Figure 3 is a transverse sectional view taken substantially on the line 3-3 of Figure 1.

Figure 4 is a bottom plan view of the tool.

Figure 5 is a longitudinal sectional view taken substantially on the line 5-5 of Figure 4.

Figure 6 is a fragmentary detail sectional view taken substantially on the line 66 of Figure 1.

Referring to the drawings by reference numerals it will be seen that the saw file, in the preferred embodiment thereof, comprises an elongated body plate 5 of wood, metal, or other suitable material to one side of which and adjacent one longitudinal edge is secured through the medium of screws or other fastening elements 6 a handle 1 that extends for substantially the full length of the body plate 5.

At the opposite longitudinal edge thereof the body plate 5 is rabbeted so as to provide at the underside thereof a longitudinal file accommodating groove 8 that extends for the full length of the body plate.

The groove 8 is adapted to accommodate therein a file 9.

In accordance with the present invention the file 9 at one end thereof is provided with an opening 10 which receives a bolt II that extends upwardly through the opening l and through a suitable opening provided in the body plate and is equipped with a nut I4 for securing'said end of the file to the body plate.

At the opposite end thereof the file 9 is provided with an elongated countersink l5 and a slot IE to accommodate a bolt ll that extends through the slot I6 and an opening provided therefor in the body plate 5. Threaded on the upper end of the bolt I1 is a nut I8, the bolts I3 and I1 thus serving to positively secure the file 9 to the underside of the body plate 5 and within the groove 8.

It will be apparent that the file 9 may be disposed at the desired position of vertical adjustment within the groove 8 and shims I9 are provided for insertion between the file 9 and the body plate 5 as shown in Figure 5 for filling the space between the plate 5 and the file 9; the shim plates l9 being arranged adjacent the opposite ends of the file, and the number of superimposed plates l9 at each end of the file will of course 5 depend upon the desired adjustment of the file.

When the device is to be used the saw 20 subsequent to the setting of the teeth thereof is placed on a fiat board or other suitable surface or working table 2| and the operator then places the tool on the top face of the blade of the saw with the file in contact with the teeth of the saw blade and the tool extending longitudinally of the blade as shown. With the tool thus positioned on the saw blade the operator by grasping the handle 1 of the tool reciprocates the tool lengthwise of the blade in an obvious manner for filing the teeth to the end that the sides of the teeth may be set or regulated or finished to the minutest degree.

It is thought that a clear understanding of the construction, utility, advantages and manner of using a tool of this character will be had without a more detailed description.

Having thus described the invention what is claimed as new is:

1. In a tool of the character described, an elongated body plate having a handle secured to one side thereof, said body plate having one longitudinal edge thereof rabbeted to provide at the underside of the body plate at said edge, a longitudinal groove, a file accommodated Within said groove, and bolt and nut means engaged with the file and the body plate for securing the file to the plate and Within said groove, and shim plates interposed between the file and the underside of the body plate for securing the file at the desired position of adjustment in spaced relation to the underside of the body plate, said file having an opening therein adjacent one end of the 4 file to receive one of the bolts, and said file at the opposite end thereof being provided with an elongated countersink, and a slot for accommodating a second bolt used in securing the file to the body plate.

2. A tool for use in filing the teeth of a raker tooth saw, said tool comprising a body plate provided adjacent one longitudinal edge thereof with a longitudinally extending handle rising from the plate at substantially right angles thereto, said plate at the opposite longitudinal edge thereof being rabbeted to provide at the underside of the plate a longitudinal groove, bolts extending upwardly through openings provided therefor in said plate at the rabbeted edge of the 5 latter and adjacent opposite ends of said plate, and a file secured by said bolts within the groove formed at said rabbeted edge, said file being provided with an aperture adjacent one end thereof accommodating one of said bolts, and at an opposite end thereof being provided with a slot elongated longitudinally of the file and opening at one end thereof through the adjacent end edge of the file, and said file on the underside thereof being provided with countersinks in the region of said bolt-accommodating opening and slot respectively.
